Thank you, I've done some research and refined what I'm looking for:
Bluetooth
Connection for monitor x3 like AOC 22B2H (HDMI, USB-C, or the MIPI connections, unsure what is needed?)
CPU: RISC-V preferred to ARM or x86
Graphics integrated
LAN x2
Mobo: I'm unsure on mini pc mobos, but needed?
Power: whatever
Ram: 16-32GB preferred, DDR5?
Storage: small is fine 32GB-256GB, nothing large like 1TB. M.2 NVMe appears to be fastest.
USB for mouse
USB for spare, for Home Assistant Zigbee bridge
Wi-Fi for hotspot
